I have an html page stored locally on my Android app assets. I want to display it within a WebView and to add some parameters to the web page.
I put all my values into a JSONArray and then I use 'addJavascriptInterface' to add this JSONArray to the webpage javascript.
But when I try to use the value in javascript, it's of type [object Object] and with a length undefined...
JSONArray json = buildJSONArray();
webView.setWebViewClient(new WebViewClient());
webView.getSettings().setJavaScriptEnabled(true);
webView.addJavascriptInterface(json, "data");
webView.loadUrl("file:///android_asset/test.html");
I trie to replace the jsonArray by a simple String, and the same thing happen...
How can I send a javascript parameter to my html page from Android ?' Apparently I've miss something with the 'addJavascriptInterface' method...
Thanks :)
